Overview
The LiveLink 4 is a battery-backed vehicle tracking and telematics unit utilising GPS, GSM / GPRS, BLE and
Wi-Fi technology.
CLASSIFICATION: PUBLIC DATE OF PRINT: 20 January 2021
Installation
LiveLink 4 units are designed to be installed both within the vehicle cab in a protected environment and
externally fitted.
Depending on the application the device may be permanently powered, or only powered periodically. In
either application, the LiveLink 4 is designed to make efficient use of the power available through the use of
sleep modes when there is no activity.
When selecting a suitable mounting location, please be aware of:
• Excessive temperatures
• Corrosive fluids
• Areas where the unit may obstruct the driver's view or impede the operation of the vehicle
• Locations that may shield the unit affecting GPS and/or GPRS reception.
• Unit and antenna separation distance of at least 20cm from all persons, animals and other
antennae or transmitters.
• Local or international regulations regarding the fitment of equipment within vehicles.
The installation must be carried out following FCS1362:2010 or later, by a Microlise approved installer. The
recommend installation to vehicles is to be mounted on 2 x M5 fixings, tightened to 2Nm.
For installation the unit must be fused on the power input at 2A, and on the ignition input at 1A using
automotive fuses and fuse holders tested to relevant safety standards appropriate for the intended country of
use.
The minimum connections to the vehicle for unit operation are listed below.

Description of operation
Providing external power is applied, or the internal battery is sufficiently charged, and the unit is within GPS
and GPRS coverage the unit will periodically (based on time and/or distance, and configuration) transmit
location and telematics information to the relevant Microlise system.
If out of GPRS coverage then messages are stored into non-volatile Flash memory for transmission later
when a GPRS connection can be established.
Whilst operating on external power the unit will charge the internal battery as required.
Two CAN interfaces are incorporated which are typically used to either listen for or request information on
automotive CAN busses.
The unit incorporates an RS232 interface which can be used for connection of a variety of peripherals, e.g.
Mobile Data Terminals, refrigeration temperature monitoring equipment, printers, sensors or other devices.
The unit incorporates six digital inputs. One is available for monitoring ignition status, another for engine run,
the remainder are general-purpose inputs which can be used for monitoring doors switches, panic buttons or
other digital signals.
A real-time clock is incorporated for time-stamping all events recorded by the unit.
The unit monitors its internal temperature. Battery charging is only permitted when the temperature is within
the specified limits of the battery pack.
The Bluetooth interface can be used for diagnostics or connection to peripheral devices, e.g. a data terminal.
A Bluetooth Low Energy interface is available for monitoring a variety of BLE devices and tags.
The unit is fitted with internal GSM, GPS, Bluetooth and Wi-Fi antennas.
The built-in accelerometer can be used to monitor harsh braking, acceleration, cornering, and any lean of the
vehicle.
The built-in modem supports four GSM frequency bands, seven UMTS frequency bands, and nineteen LTE
frequency bands (see Technical Specification section for details).
The LiveLink 4 supports the application of firmware and configuration to allow specific user and vehicle
profiles and functionality. These are applied by Microlise only and are not accessible to the end-user. The
firmware and configuration do not affect the performance of the integrated RF modules, and changes to
firmware and configuration do not affect the approval compliance of the product.
Service / Repair
The LiveLink 4 contains no user tuneable or serviceable parts. Service of the LiveLink 4 should only be
carried out by authorized personnel.
